The 47-year-old actor - who raises six children with partner Angelina Jolie - says financial success is no longer so important to him because it doesn't necessarily mean he produces good work.

He said: "I like films that make money. But I've been less concerned with that of late. I've found with one period where I was thinking that way, I made bad choices."

Brad can next be seen in baseball movie 'Moneyball' and while he thinks it can sound "counterintuitive" to have such a famous star leading the cast of an underdog movie, he likes the fact that using his name can get the projects he likes onto the big screen.

"That's how they first came into contact with the book, the studios were having seminars with Billy on how to apply his theories to the film business.

"That I ended up in the film is counterintuitive to the teachings but I wanted to see it get made. That's all I want; to see movies get made that I believe should be made. And if my name - whatever it may or may not be worth - can help in that process, then that's why I'm going to do."
